Meta-Analysis
Down syndrome (DS) is a genetic disorder associated with early-onset periodontitis and other periodontal diseases (PDs). The present work aimed to systematically review the scientific literature reporting studies in vivo on oral microbiota features in subjects with DS and related periodontal health and to highlight any correlation and difference with subjects not affected by DS, with and without PDs. PubMed, Web of Science, Scopus and Cochrane were searched for relevant studies in May 2021. The participants were subjects affected by Down syndrome (DS) with and without periodontal diseases; the study compared subjects with periodontal diseases but not affected by DS, and DS without periodontal diseases; the outcomes were the differences in oral microbiota/periodontopathogen bacterial composition among subjects considered; the study design was a systematic review. Study quality was assessed with risk of bias in non-randomized studies of interventions (ROBINS-I). Of the 954 references retrieved, 26 studies were considered. The conclusions from the qualitative assessment of the papers revealed an increasing knowledge over the last years of the microbiota associated with DS and their periodontal diseases, in comparison with healthy subjects and subjects with other kinds of mental disabilities. Few data have emerged on the mycobiome and virobiome of DS, hence, further investigations are still necessary.

Colorectal cancer (CRC) is the third cause of cancer-related death worldwide. It has been estimated that more than one million new cases occur every year. Several studies have investigated the role of host bacteria as agents protecting against or increasing the risk of CRC, but few have assessed the fungal microbiome in patients with CRC. Fungal dysbiosis has been studied in colorectal diseases (e.g. inflammatory bowel diseases), but few researches compared the fungal microbiome of CRC patients with those of controls. The current study represents a systematic review aimed at assessing the expression and diversity of fungi in patients with CRC and non-CRC individuals. Here, we discuss the fungal species that could be implied in CRC development and alterations that can be induced by the presence of CRC, and the potential implications for future research.
